Application August 5, 1954, Serial No. 447,946

7 Claims. (Cl. 3031) This invention relates to an instrument for shaving and trimming hair and more particularly to a cutting instrument for clipping, trimming and shaving hair and the like.

The present invention proposes certain improvements in my co-pending application Ser. No. 435,554, filed June 9, 1954, for a cutting instrument, namely the provision of a removable stationary blade for shaving the hair and coacting therewith a pair of oppositely disposed combs which are easily and readily adjustable relative to the cutting edge of a blade.

It is another object of my invention to provide a manually operable cutting device which is economically and simply constructed and in which there are combined a hair combing and hair cutting or shaving means.

Other objects of the present invention are to provide a cutting instrument bearing the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is easy to use and eflicient in operation.

Other objects will become apparent from the following description taken in connection with the attached drawing, showing an illustrative embodiment of the invention and wherein:

Figure 1 is a side elevational view of a preferred embodiment of a cutting instrument embodying the features of the present invention;

Fig. 2 is a view similar to Fig. l but showing the adjustable comb members in their extreme outer position;

Fig. 3 is a view similar to Fig. 2 but showing the adjustable comb members entirely removed and the stationary shaving blade and cartridge therefor partially removed; I

Fig. 4 is a side elevational view shown partly in section and broken-away to illustratethe interior construction thereof;

Fig. 5 is a fragmentary vertical sectional view taken along the line 55 of Fig. 1;

Fig. 6 is an enlarged vertical sectional view taken along the line 66 of Fig.5; and

Fig. 7 is an exploded perspective view of the removable cartridge and shaving blade.

Referring now more in detail to the drawings wherein like numbers refer to like parts throughout the several views, there is provided a cutting implement indicated generally at 10 and including a pair of complementary positioning or holding members 11 and 12, substantially as illustrated (Fig. 5), of the type set forth in my copending application. As disclosed in my co-pending application, the positioning members 11 and 12 are provided at their upper ends with the laterally aligned serrations or teeth 13 which mount therebetween a pair of oppositely disposed stationary cutting blades similarly serrated along their upper edges and a movable cutting blade intermediate the stationary cutting blades and also serrated along its upper edge.

The positioning member 11 is provided with a lateral projection 14 to be used as a detent, extending from the end thereof as shown more clearly in Figs. 1 through 4 inclusive. 7

In order to efiect the desired reciprocating longitudinal movement of the aforesaid movable blade within the device and against the action of a spring, not shown, a pair of manually operable leverage members 15 and 16 are provided and are pivotally mounted at their inner ends intermediate the positioning members 11 and 12, one of the leverage members being in mesh with the other and forming a cam surface which moves the movable cutting blade upon the drawing together of the levers, as clearly set forth in my co-pending application. A channeLshaped thinning stop 17 is pivotally connected to and straddles the leverage member 15 by means ofa pin 18, the stop 17 being rotatable downwardly at substantially right angles to the leverage member 15 whereby to limit the drawing together of the leverage members 15 and 16 and thereby the displacement of the movable cutting blade, as set forth in my co-pending application. In the practice of the present invention, adjustable means are provided along the lower portion of the jaw positioning members 11, 12 whereby the back of the neck may be shaved and the neck either trimmed or feathered. As shown in Fig. 5, the jaw positioning member 12 is integrally formed with a thickened portion 19 which abuts the inner face of the jaw positioning member 11 and providing a shoulder 20, the jaw positioning members being secured together by means of the through screws 47. An elongated member 21 of substantially inverted U-shaped cross section is slidably disposed below the thickened portion 19 in abutment with shoulder 20 thereof. The opposite sides of the member 21 are integrally formed with a pair of laterally aligned, longitudinally spaced cylindrical projections 22 which ride in slots 23 provided in the positioning members 11, 12 (Fig. 3). It will be noted from Fig. 5 that the projections 22 extend outwardly beyond the outer faces of the positioning members 11, 12 and also serve to retain the elongated member 21' in sliding abutment with shoulder 20. The channel-shaped member 21' is integrally formed with an externally threaded extension 24 which is received within an opening 25 provided in the positioning member 12. v v

The positioning members 11 and 12 are provided with laterally aligned cut outs 26 exposing a portion of the externally'threaded extension 24 and within which'are positioned an externally knurled, cylindrical nut 27 screw threaded onto'the extension 24. Thus, as the nut 27 is manually rotated, the externally threaded extension 24 will be displaced longitudinally therethrough whereby to adjust the projections 22 longitudinally within their slots 23.

As shown in Fig. 5, the lower end of the positioning member 11 is thickened, as at 28, and integrally formed above this thickened portion with an inwardly extending longitudinal projection 29 forming a shoulder 30 with the thickened portion 28, thelower end of the jaw positioning member 11 being curved inwardly, as at 31,

A rectangular cartridge 32 is slidably disposed on the inner face of the thickened portion 28 with the upper edge of the cartridge in slidable abutment with the shoulder 30 and the lower edge thereof supported on the in-' wardly curved portion 31. The face of the cartridge 32 remote fromthe positioning member 11 is integrally formed with a longitudinally extending boss 33 which is received in a correspondingly shaped elongated opening 34 provided in a double edged, stationary cutting blade 35 (Fig. 7).

The inner face of the lower portion of the jaw positioning member 12 is integrally formed with a thickened portion 36 which bears on the adjacent face of the boss 33 whereby toretain the parts in the sliding assembly of Fig. 5, the lower end of the jaw positioning member being curved inwardly, as at 37; The cartridge 32 at one end is integrally formed" with a flat head 38 adapted to abut the ends of the. jaw positioning. members 11, 1? when the cartridge is disposed within the device as shown in Fig. 4, the head 38 servingv to facilitate the remcvarrof the cartridge and'blade, as, shown in Fig. 3. It will' be noted that the upper longitudinal cutting edge-ofthe blade 35 is received infreely spaced rela- 't'io'nship within the channel-shaped member. 21', while the lower longitudinal cutting, edge thereof. extends downwardly; between and in freely spaced relationship to the inwardly curved ends. 31, 3.7..

The cartridge 32 and. blade 35. will.normally be. retaiiied. with the device by means. of frictional engagementlw'ithfthepositioning members. 11, 12 butmay be readily and. easily withdrawn by. means of the head 38 to. permitthe blade 35 to be removed from the boss 33 'andreversed tov provide a new cutting edge or to be replacedby anew blade.

Apair of complementary, movable comb elements 40 areprovided and include the vertical plates 41 in sliding contactwiththe opposite outer. faces of the positioning members 11, 12. and the dependingcomb teeth elements 42. It will be noted that the upper portions of the combzelements 42.. (-Fig. extend outwardly anddownwardly from the positioning members 11, 12 and are then flared. inwardly coming together directly below the cutting. edge of the blade 35, the lower ends of. the comb elements.42 at this point beingintegral with each other andserving to retain the vertical portions-41 in resilient contact with the sides of the jaw positioning members 11, 12.

A. pair of complementary, rectangular plates 43 are. suitably secured to the inner faces .of each of the vertical portions 41 of comb elements 40, each of the plates 43 being-provided with the vertical slot 44 extending upwardly from the lower edges thereof. and into which extend the projections 45 on opposite faces of the positioning, members 11, 12 wherebyto prevent. the'comb members 40 from .moving longitudinally while permitting their lateral movement.

The: upper edges of the vertical portions 41 are integrally formed with laterally extending flanges-45 which serve to abut the upper edge of-the plates-43.

The plates 43 are also provided with a pair of inclined slots- 46 (Fig. 6) within which ride the projections 22 which extend outwardly through the slots 23. Thus, upon longitudinal movement of the'projections 22, the plates 43 and their comb elements 40 will be forced laterally inwardly or outwardly, depending upon their direction, whereby to vary the distance between the lower ends of the comb elements 42 and the lowermost cutting edge of the blade 35. The longitudinal movements of the aforesaid projections 22 will, of course, be effected simplyby rotating the nut 27. Thus, the implement may be used to shave the back of the neck or the baseof the head by the cutting action of the blade 35 in cooperation with the comb elements 42, the depth of out being regulated in an easy and ready manner by the externally knurled nut 27. The comb elements 42 beingintegral with each other below the cutting edge of the blade 35 will prevent the skin from being cut by blade 35 even though theblade is inits outermost position relative to the ends of: the comb elements 42 (Fig.1).

The through screws 47 serve to retain the position with the accompanying drawings, it will be noted that my invention includes the Comb elements40.adjustable- 4. relative to the cutting edge of blade 35 and serving to position the'hair before cutting it. It' will also be noted that the comb elements 40 are adapted to trim or feather the hair at the back of the neck in conjunction with the stationary blade 35 mounted therebetween. It will also be noted that the externally knurled nut 27 will effect the desired adjustment of the blade 35 relative to the joining ends of the comb elements 42. Thus, a device has been provided which may be easily'andi readily used for hair cutting, hair thinning, trimming and feathering.

It will be noted that the construction shown and described will serve effectively to accomplish the objects stated above; It isto be understood, however, that the construction disclosed above is intended merely as illustrative of the invention and not as limiting, as various modifications therein may be made Without departing from the invention as defined by a proper interpretation of the claims which follow.
